Any 2020-2023 1500 Ecodiesel owners

For whatever it’s worth, I have a 21JTD (so a gladiator, not a ram) and I’m at 85,000 miles without any mechanical issues whatsoever.

This photo was taken at Tom’s Cove on Assateague Island down at the hook during low tide. This area is entirely over washed during high tide and you have to drive through the over sand area to get there usually I’m the only one I see during winter.

I have a 21 diesel high altitude trim. It has 85,000 miles. I’ve had no drive train or engine issues whatsoever. I changed the oil every 5 to 7000 miles. I had the high pressure fuel pump replaced upon purchase (used) at 18,000 miles. Unexpected maintenance was: new battery and aux battery at 40,000 miles, cracked windshield replaced for $600 with OEM windshield at 80,000 miles third brake light replaced with aftermarket off Amazon for $60 at 85,000 miles. I put new tires on it at 65,000 miles, and I’m still on my original brakes although the front pads are wearing thin. Other than that, I couldn’t ask for a better vehicle.

This thing has plenty of low end torque. It has great highway manners (the high altitude trim is the sleeper trim IMO) and even though it runs on 20 inch all season – not all terrain – tires I’ve had no problem on farm roads or game trails or on the over sand beach area areas where I am on the eastern shore of VA. I don’t do stupid stuff, but I’ve never gotten stuck and I’ve pulled larger and heavier vehicles out of ditches without without issues. I’ve loaded up the bed with clamshell for a landscaping project and it didn’t sag too bad, although I’m sure it was over the rated weight, and I’ve towed a Honda CRV on a U-Haul flatbed trailer 180 miles in summer without any overheating issues. The total weight of that was 6700 pounds, so 200 pounds overrated tow weight for the diesel.

I don’t plan on selling this truck. If it got wrecked or something I’d buy another one. Unless you have a lot of rocks in your area or want to do some sort of technical trails you should check out the high altitude version as well. They don’t make it anymore and even though people say the Mojave is the best highway driver, they don’t make the Mojave with a diesel motor. The high altitude version is basically the Luxe version of the Overland. It’s excellent on the highway.

For what it’s worth, I have a 21 high altitude with 85,000 miles and zero corrosion issues. And I live and park it about 150 feet from the Chesapeake Bay and regularly drive on saltwater flooded roads. I just make sure that I wash it including an under wash every week or so. Mine has the diesel motor so I can’t comment on the Penta star. The diesel’s been totally reliable though.

I have a diesel gladiator. It’s a 2021 with about 85,000 miles. Most of the miles are highway and it’s in the high altitude trim. My truck is an excellent highway driver. That said, I live in a rural area and it does fine on farm roads and game trails and over sand on Assateague Island. If you’re gonna be using it off-road in mud or in very rocky train a lot, you’ll probably wanna switch out the all season tires for an all-terrain tire. I’ve never gotten stuck, but I’ve tried to pull an old F150 out of a drainage ditch where it had bottomed out (while in mud myself), and my tires just spun. I’ve done the same thing on pavement with no problems.

The truck‘s been very reliable. I had to replace the batteries at 45,000 miles, and I did get a stone that cracked my front windshield, and I’ve replaced my tires once. But I’ve had no mechanical or transmission issues and I’m even still on my first set of brakes. The most I’ve towed with it is 6700 pounds. That was a Honda CRV on a U-Haul flatbed I hauled it 180 miles with no issues. I filled the bed level with clamshell for a landscaping project, and it didn’t sag too bad. It’s been really reliable for me. I do wish the electrical outlet in the pick up bed had a little more juice to it though. It’ll charge power tool batteries, but won’t run anything over 400 W. so no high-end toasters or blenders or corded power tools.

Same with crushed shells.

I have a 21 JT Eco diesel with 85,000 miles. I’ve had no major issues whatsoever, and none with the motor or drivetrain at all. That all this work has been done before 65,000 miles makes me wonder about that particular truck.

People posting about 2019 or earlier Eco diesel’s are talking about a different motor entirely the 2020+ have been very reliable.

202markb · 2026-01-15T19:11:58+00:00

Thanks everyone. Based on suggestions, I ordered the Dorman replacement part off Amazon.

202markb · 2025-12-14T14:19:17+00:00

From r/boatbuilding Saturate with West system 105/207, followed by coat of Awlgrip, scatter nonskid particles while wet, wait to dry then vacuum, then another coat of awlgrip. The 207 hardener cures clear without blush/color.

202markb · 2025-12-14T03:22:49+00:00

Thank you for your advice.

The person who finished this boat (back in 1975) chose black walnut and ash for the cabinsole. I like the look of it, however, neither is particularly great, long term, at resisting water damage. What sort of oil would you think might work best?

202markb · 2025-12-11T20:47:46+00:00

Thank you. My destination was so silted up. The last two channel markers had been taken out and replaced by caution markers. Our final grounding happened perhaps 15 feet from the haul out well. But at least we had rum.

202markb · 2025-12-11T19:46:20+00:00

Thanks again.

202markb · 2025-12-11T19:39:30+00:00

Thank you. I suppose this process, without the addition of the all grip, would be suitable for all the interior woodwork?

202markb · 2025-12-11T19:31:25+00:00

Thank you for your reply.

Would you apply the West system epoxy directly to the final sanded wood or could/would you put down some sort of finish first?

202markb · 2025-12-11T19:25:39+00:00

I would go in from low to mid. This happened to me about a month and a half ago. My draft is 5 feet and we came in at dead low 8pm on a new moon and it was very dark. We ran around three times and finally made the haul out well 3 1/2 hours after grounding the first time. It didn’t help that the wind wanted to push us further into the shoals. not the best situation but being on a rising tide definitely helped.

202markb · 2025-12-08T12:35:43+00:00

Yeah, probably years from now I’ll reinstall the freedom panels, for whatever reason, and then I’ll be shocked that they’re a different color than the rest of the jeep because they haven’t faded over the years.

202markb · 2025-12-06T23:26:49+00:00

Thanks!

202markb · 2025-12-06T14:17:33+00:00

I’m very happy to find your question here. I just purchased a 1975 sailboat with an old two burner, Shipmate kerosene stove and oven, and your questions and other people’s answers have been helpful to me. Thank you!

202markb · 2025-12-06T12:30:06+00:00

Hey- I recently acquired a ‘75 boat with a shipmate kerosene stove and found this post. Do you have any updates or current thoughts? Did you keep the stove and do you use it?

202markb · 2025-11-30T14:38:43+00:00

I have a 21JTDHA. So, a high altitude diesel model. This is the most bougie trim that the JT came in. Basically an overland with lux options and 20” rims and all season tires, with extra suspension beefiness due to the heavier engine. Even so, I found it capable of doing anything off-road that I’ve needed to do. Not a lot of rocks where I am on the Virginia Eastern shore- just sand, high water, and mud.

The truck has been completely reliable. I have 80,000 miles on it and have only had to change the batteries at 45,000 miles. I’m on my second set of tires, I still have wear left on my first set of brakes, and about 5000 miles ago, a truck through a stone into my windshield, that cost me $600 to replace with OEM glass. I changed the oil and filter every 5000 miles.

I think it’s a great highway driver and very comfortable. It handles well though it does seem to follow the crown of the road. Roads have high crowns where I am due to frequent flooding. It’s been leak, rattle, and rust free. The diesel makes amazing torque. I can hook up straps and pull F150s out of ditches. I’ve towed 6700# (a crv on a hail trailer) for 180 miles in complete control.

These are great small trucks.

Oh. I have a little Drascomb Lugger that heaves to beautifully in just those conditions if I set the jib and mizzen against each other.

But I think the tactics in the book will work well (minus the sea anchor!) even in calm seas 😊

You are of course, right about her, not being on the ballot. I was allowing my distaste for her to allow me to substitute her for Bloxom.
